Im a 26 year old female who is extremely worried about my health. Im 5ft and weigh 7.7stone
I have been getting colds alot and am currently ill with what i assume is a chest infection.
I eat well but i do like a drink and occasional smoke.

My blood test all seem fine but i have so many symptoms that i worry i have something serious. Symptoms are:

Excessive sweating
Hands go numb in cold (normally 1 or two fingers on each hand)
Painful clicking wrists (that has subsided lately)
Rapid heartbeat (110BPM at rest)
Heat rash in sun or hot shower (on chest or sometimes tummy)
Im not sure if im paranoid or need to stop being a hypocondriac.

Please help
